Takes the same screen as a 1490 or 1450 and the screens are not expensive. No traffic capability or Bluetooth on this unit that I have found. The 50LM is a stripped down version of the 1450. The weakness is the on-off button assembly and the fragile Garmin charger port. The on-off assembly is light duty and tends to break away from the case. Not found any way to fix it. Non working ones sell for $35 on the bay so sounds like you have got a good deal.
